This is because the airborne perlite particulates (to be very scientific and, I suppose, pedantic) irritate my lungs just like any other form of particulate. For example, I wear the same mask when sweeping my garage, working in the unfinished attic, and working with dry soilless mix (prior to my wetting it). I don't see any reason for wearing a mask after I've combined the perlite and soilless mix. | |

As the NIH reference says, any dust that was in the perlite you bought is no more hazardous than any form of "nuisance dust", though it can contain a small proportion of silica (i.e. sand) which can be carcinogenic. Don't forget the building panels in your walls and ceiling probably also contain perlite as a lightweight filler material. Wearing a mask 24/7 is paranoia IMO. | |
